[movies]Small Dynamic Events on the Sun Captured by Hinode
The X-ray Telescope on the Japanese/NASA mission Hinode has been observing the full Sun for an extended period. In this movie significant small-scale dynamic events can be observed as well as the slow maturation of many active regions now visible on the solar disk. Hinode is joint JAXA/NASA mission to study the connections of the Sun's surface magnetism, primarily in and around sunspots.

[texts]Computational Simulation of Damage Progression of Composite Thin Shells Subjected to Mechanical Loads - Gotsis, P. K.
Defect-free and defected composite thin shells with ply orientation (90/0//-75) made of graphite/epoxy are simulated for damage progression and fracture due to internal pressure and axial loading. The thin shells have a cylindrical geometry with one end fixed and the other free. The applied load consists of an internal pressure in conjunction with an axial load at the free end, the cure temperature was 177 C (350 F) and the operational temperature was 21 C (70 F)...

[movies]Science Nation: Sunspots Revealed
Sunspots have fascinated mankind right from their first detection. Their mere existence challenged science and philosophy when it was recognized that the sun, once believed to be pure and unchanging, was indeed not. Now, state-of-the art telescopes, combined with the muscle of a supercomputer called "Bluefire," are allowing scientists to come to a physics understanding of sunspots and to accurately model their structure and dynamics.

[texts]A Coupled Soil-Atmosphere Model of H2O2 on Mars - Bullock, Mark A.
The Viking Gas Chromatograph Mass Spectrometer failed to detect organic compounds on Mars, and both the Viking Labeled Release and the Viking Gas Exchange experiments indicated a reactive soil surface. These results have led to the widespread belief that there are oxidants in the martian soil. Since H2O2 is produced by photochemical processes in the atmosphere of Mars, and has been shown in the laboratory to reproduce closely the Viking LR results, it is a likely candidate for a martian soil oxi...

[movies]Delta Sunspot - Naval Research Laboratory
When a large bundle of magnetic field lines breaks through the Sun's surface, a sunspot can form. Sometimes, a smaller spot will emerge nearby, creating a magnetically complex region where particles are energized and then violently expelled. Supercomputer models show that rearranging magnetic field lines enables this process. Note: A animation of the magnetic field of a sunspot, where the magnetic field at the Suns surface is colored blue for strong fields pointing into the sun and red for stron...
